ActionScript 3.0 :: Check If A Movieclip Has An Event Listener On It?
Mar 24, 2010Is it possible to check if a movieclip has an event listener on it?

View 2 RepliesI am trying to create an event listener to check that a function has completed before the next action is run. In simple terms I have a module that is opened and closed via two functions... module_open() and module_close().Each function has tween elements that must complete before the next element is processed... i.e the next function, etc.This is the code I have ( have attempted to create an event listener but I seem doing something wrong. I am not even sure that it is possible to create an event listener that checks for a function finishing before calling the next function.
Code:
function onAbout(event:Event):void {
module_close()
module_close.addEventListener(Event.COMPLETE, onClose_Complete);
[code]....
Is their a way to check if an event listener already exists to remove it? stage.addEventListener(MouseEvent.CLICK, clickdownfunction); Basically, I want to remove the listener, but sometimes it has already been removed, so I want to check if it exists and if it does, then remove it.
View 4 Repliesi'm trying to check if a movieclip has an event listener with a sepecific function bound to it. The hasEventListener function only accepts one parameter (the listener). What i would need would be an hasEventListener that accepts a second parameter, namely the function that is bound to it.
Code:
if (!mc.hasEventListener(MouseEvent.ROLL_OVER) {
mc.addEventListener(MouseEvent.ROLL_OVER, overHandler);
}
but what i would need is:
Code:
if (!mc.hasEventListener(MouseEvent.ROLL_OVER, overHandler) {
mc.addEventListener(MouseEvent.ROLL_OVER, overHandler);
}
because i bind more than one ROLL_OVER listeners to that mc.
i've not tried to do anything odd with eventListeners up until now. i have a movieclip with multiple frames that i use AS to attach a textfield to it. problem is i have a eventlistener for when the mouse rollsover the movieclip to go to frame 3 of the movieclip.
[Code]...
what's causing the textfield to suddenly take precedence and how do i stop it. when i trace the evt.target - it is my movieclip.
I've an array of movieclips created via code that have some textfields. Then i have added some listeners to the movieclips.
Here the code:
Code:
arrNot[i].addEventListener(MouseEvent.MOUSE_OVER, titoloOver);
private function titoloOver(e:MouseEvent){
var nome:String = e.target.name;
TweenMax.to(curs,1 ,{y:contMain.getChildByName(nome).y + 23});
}
This code moves a cursor calculating the y coordinate depending the moviclip that is mouse overed. Now the movieclips have some textfields so when i mouseover the movieclips all works ok but when i mouseover the textfield i receive a #1009 error.
way to trigger a functiont when a movieclip animation finishes? I figure an eventlistener could handle this, but not sure the best way to go about it.
View 7 RepliesI have a project with 15 dynamically created MovieClips on. The clips are images loaded from XML.As each one is loaded I assign an id to it. screen.id = [i];Now normally I would add an event listener to trigger each of these to "Do Something" but I want it to be an automatic process. So I have set up a function to create a random number between 0 and 14 with the idea that I can use the number to help reference the MovieClip with the id of the randomly generated number...But I don't know how to go about this Something like...
Code:
Select allprivate function randomNumber(low:Number, high:Number):Number
{
var low:Number = low;
var high:Number = high;

Adding addEventListener too a Child object
I am programming a "build a tower" game. After removing the event listener from the first movieclip, flash won't add the event listener to the by as3 to the stage attached new movieclip.

for one of my project I need to recive some x,y data from a socket connection. I recuired do some movement for moveclips those has the x,y in its bounds. kind of mouseover event.
what I fegured out is, if I can dispatach a event and add a listenr to all my movieclips the moveclips will know that new data recived and it will check that the number and do appropriate action.
but the problem is I can dispatchEvent but if I add a listener to my movieClips it doesn't work.
/// this way works ///
function readResponse():void {
var str:String = readUTFBytes(bytesAvailable);

I'm thinking of making a movieclip which stops itself at certain points (just with stop(); at certain keyframes in the movieclip timeline), then the user is prompted to continue the clip.
What is the best why to listen for the stopping of the movieclip? I think I want an event listener that detects when the movieclip is stopped, but I don't know if there is one.
I have ActionScript inside a movie clip running a scrollbar.[code]...
I need to remove the Stage Event Listener (stage.removeEventListener(MouseEvent.MOUSE_UP, thumbUp)) when I switch menu items. How can I call the removeEventListener for the stage from outside the movieclip?
The parent movieclip is called about_mc and when you click away to another page it tweens out. I really just want to about_mc.stage.removeEventListener(MouseEvent.MOUSE_UP, thumbUp).
I have a slideshow that loads an image via XML, then adds said image to a placeholder inside a movie clip, and then proceeds to play a little sliding animation via the movie clip. What I need to do is figure out how to get an event that the movie clip is finished and sitting back on frame 1 so that I can run a "nextImage" function that loads the next image from the XML. I'm pretty new to actionscript, and I can't for the life of me figure out how to properly handle what should be a simple event. If I put a simple listener at the end of the movieclip, it doesn't talk to the main script at all?
View 6 RepliesHow do I make an event listener that will tell my movieclip to gotoAndPlay a different frame if x is < than 100?
View 1 RepliesI have created event listeners for a particular movieclip.Insidet this movieclip there is so many objects.When ever I click on the parent movieclip the event listener calls the function for the child object. I had tried removeEventLIstener()
import flash.display.MovieClip;
import flash.events.Event;
import flash.events.MouseEvent;
var info:MovieClip=new MovieClip();
info.graphics.beginFill(0x000000,0.35);

I want to delete mc's parent
I want to run a function when a certain movieclip enter a specific frame. The problem is it run the function repeatedly. I only want it to run once each time the movieclip change from one frame to another is there an event Listener that does it ? (can't put the code on each frame of the movieclip to sloppy and long)
View 0 RepliesI'd like to simply scale down a movieclip (that I'm treating as a button) when the user presses their mouse button. When users release the mouse button, I want my button to scale back to it's normal (.scaleX = .scaleY = 1) size. My button also has listereners for a ROLL_OUT event to turn off (.alpha = 0) a highlight movieclip that rests atop movieclips showing the different states the button can be in.
When I roll over the button, the higlight comes, but there is an annoying flicker problem. For some odd reason, when I press the mouse button the ROLL_OUT event handler function is called, yet I didn't scale the movie down enough for the cursor to be off of the actual button itself. I do not want that flicker. I'm not sure why ROLL_OUT is being called even though the event is clearly a mouse down, and within the mouse down event handler I am scaling the button movie clip, but not enough to remove out from under the cursor. In other words, if I click the button at its registration point, a flicker appears.
Here's my code.
//this add all the appropriate listeners to the button private function addMouseListeners() { this.addEventListener(MouseEvent.MOUSE_OVER, mouseOver); this.addEventListener(MouseEvent.MOUSE_DOWN, mouseDown); this.addEventListener(MouseEvent.ROLL_OUT, rollOut); this.addEventListener(MouseEvent.MOUSE_UP, mouseUp); }
[code]....
why my rollOut function is being called when the mouse button is pressed, and called once more when the mouse button is released.
How can I check if the stage contains a movieclip on a specific x and y location on the stage?I'm building a colour-guessing game. The purpose is to walk a path through a generated field of hexagons, each assigned a random colour (yellow, red, blue or green), based on what soundfile you hear. So if you hear "yellow", you have to click a yellow tile etc.But because I want it to be a path, and the colours of the tiles are randomly generated, I have to check which colours border the currently active tile. I literally have no idea how to do this. I thought this might work but it doesnt:
if ((this.tile.y == (event.currentTarget.y - 64)) != null) {
//add the colour of this tile to array
}

I am trying to learn JavaScript and I am wondering whether JavaScript has a event listener just like ActionScript's ENTER_FRAME. Basically, I want this event listener to listen "all the time" not just wait for any particular instance (mouse click, keyboard event) of event.
View 3 Repliesif I have an event listerner (mouse, keyboard, enterframe,....event) that is being triggered, and when it finishes its event, something that is able to detect the finished event listener and fire out another sets of event.
It works more like MOTION_FINISH in TweenEvent, but it is only available for TweenEvent only, what if I want to detect a mousclick, keyboard, enterframe or even touch event?
My stage has about 25 buttons on it. Each button when pressed to tweens the background to some random x/y coordinates and then loads an external swf file.This is all working, but the timing is off. How can I wait for the initial background tween to end before I make the loader call to the .swf file.Currently each button's behavior is called on the MouseEvent.CLICK event which calls a function that knows its unique filename.swf. I know you can add the MOTION_FINISH even to the tween event but then I would have to call a new function and lose track of the button that initially called it.
View 3 RepliesI'm moving on to my next massive programming project and I'm trying to decide whether I should code it in as 2.0 or 3.0. I came across the new click event model in 3.0. Right now it's looking like a pain in the butt to me. So now I have to make a function and add it as an event listener? what the hell? What's the benefit? I understand stuff like this makes AS a more complete language but it's kinda annoying.
View 1 RepliesThis is a very basic question but I can't seem to find an answer. I have a mouse over event and have created the buttons with the mouse overs which is working great. I created the actionscript to go to a specific web page when a user clicks the button. Now, I need to add a label to the mouse over so when someone mouse's over any area of the button, it will show them a particular name for the button.
I am sure that this can be done using actionscript in a mouse event roll over command but I can't figure out what I need to show the text. Here is where I am:

how can i access event.target outside event listener method.say for example
my_mc.addEventListener(MouseEvent.CLICK, onC);
function onC(e:MouseEvent):void
{
var m:MovieClip = e.target as MovieClip;
}
trace(m.totalframes);/// not working
now what if i want to get totalframe property of m instance, in short for every movieClip clicked.
I am doing this inside a module containing viewstacks and their childs.Calling onInit() on creationComplete of module.When I am inside one of the childs of a viewstack of this module and press Enter, it doesnt not invoke the listener function at all (bp inside this does not get hit).
private function onInit():void{
this.addEventListener(KeyboardEvent.KEY_DOWN, keyPressed);
}[code]..........
This might be more of a subjective question, but is it generally best practice to have one dedicated method per event-types that you add an event-listener?
Such as:
myButton.addEventListener(MouseEvent.MOUSE_OVER, onMouseOver);
myButton.addEventListener(MouseEvent.MOUSE_OUT, onMouseOut);
//Somewhere else in the code...
[Code].....
And if you had a MouseEvent.MOUSE_UP, MouseEvent.MOUSE_DOWN and other relevant MouseEvents event-listeners to watch for, you could even set a switch statement to handle all the various MouseEvent types.
I have these buttons in a movie clip and I would like to have only one event listener for the parent, using event.target to point to the children. I have also tried event.currentTarget, and it didn't work.here is the code that works:
test01.abtn.addEventListener(MouseEvent.ROLL_OVER, mouseHandler);
test01.bbtn.addEventListener(MouseEvent.ROLL_OVER, mouseHandler);
test01.cbtn.addEventListener(MouseEvent.ROLL_OVER, mouseHandler);[code]....
It is only targeting the movie clip, not the buttons inside the movie clip.
